Summary Description: RPM's surging during pump mode
Summary
On January 10, 2011 the Office of Defects Investigation (ODI) opened Preliminary Evaluation (PE11-001) based on a product improvement program (PIP) (ODI TSB # 10036912) submitted by Caterpillar dated August 18, 2010. The PIP was for engine RPM's that could surge while in a water pumping mode on 2005 through 2009 Pierce fire trucks equipped with a Caterpillar C9 engine.This engine surge could cause a fluctuation in water pressure that is being directed onto a fire through a hose.The bulletin states that this condition in conjunction with other factors or circumstances could result in a risk of personal injury or death.Caterpillar's product improvement program released information involving the installation of new engine software on the subject vehicles.On April 11, 2011 ODI received Pierce's response to ODI's Information Request (IR) letter.Based on the information received, an ODI investigator contacted several fleets and complainants regarding this defect phenomena and everyone contacted expressedconcern related to the inherent danger involved with pressure oscillations in a fire hose.Several fire fighters stated that the frequency of failure even after Software fixes have been performed per the PIP are still happening.In a supplemental IR letter dated May 27, 2011 Pierce identified a total population of 241 vehicles with the C9 engine from MY 2005 - 2008. Pierce also specified that they had 15 unique complaints coupled with 2 complaints from Caterpillar; totaling 17 consumer complaints.These consumer complaints were for MY 2006 through 2008 fire trucks.Pierce had 2 warranty claims while Caterpillar had 19 warranty claims, totaling 21 warranty claims for this investigation.ODI notes that the complaints applied to 5 vehicles and the warranty claims applied to 5 different vehicles (based on VIN).There were multiple complaints or claims on one vehicle in some cases.An ODI investigator spoke with a fire chief in Sherwood, AR who alleged a Caterpillar representative, on several occasions, came to his fire house to fix the problem of engine surge while in water pumping mode.The Caterpillar technician installed several updates to modify the software which communicates with the engine and its fueling strategies (i.e. idle function).Allegedly, after each attempt to fix the problem a fire fighter would alert the fire chief that the problem persisted in spite of constant updates.The result of this malfunction puts fire fighters at risk. ODI is concerned that a fire hose that does nor function properly has safety ramifications to the user of the fire hose and others dependent on its performance.This Preliminary Evaluation is being closed and upgraded to an Engineering Analysis (EA11-008).

Summary Description: Brake line corrosion failure
Summary
On January 11, 2011, ODI opened EA11-001 to investigate allegations of premature brake line corrosion failure in model year (MY) 1999 through 2003 General Motors (GM) full-size pickup trucks and sport utility vehicles sold or registered in the following region of the United States that NHTSA has viewed as salt states for investigations of corrosion related issues:Connecticut, Delaware, District of Columbia, Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, West Virginia and Wisconsin.The subject vehicles represent the first five MY's of GM's GMT800 platform production, of which approximately 2,038,504 vehicles were sold in salt states (the subject vehicles).The GMT800 platform includes the following vehicles:1999-2007 Chevrolet Silverado and GMC Sierra 1500, 2500 and 3500 series pick-up trucks; 2000-2006 Chevrolet Suburban, Chevrolet Tahoe and GMC Yukon sport utility vehicles; and 2002-2006 Cadillac Escalade and Chevrolet Avalanche sport-utility vehicles.General Motors produced a total of approximately 10,427,062 GMT800 vehicles for sales in the United States, including almost 5 million that were sold in salt states.Although there are over 60 different brake pipe routing configuration used in GMT800 vehicles, with the exception of the rear crossover pipes in MY 200x-2007 vehicles that changed from rear disc to drum brakes, all of the vehicles use brake pipes from the same supplier with a common double-wall, brazed steel pipe design with a combination of hot dip Zinc-Aluminum corrosion protection coating and Aluminum paint outer layer known in the industry as AlGal (ASTM-B750). ODI analysis of field data regarding GMT800 vehicles identified a total of 3,645 complaints of brake pipe corrosion failures, including 107 alleging crashes, and 40 injuries.Though only 20% of total GMT800 production, due to age and region the subject vehicles account for a disproportionate share of the failure experience; with 2,702 of the complaints (75%), 88 of the crashes (82%) and 20 of the injuries (50%) reported in those vehicles.Analysis of the complaints showed strong correlations to vehicle age and region.For vehicles with less than 8 years of service, the complaint rates were minimal for all regions.In the salt states the failure rates begin to climb as the vehicles advance in age, particularly in the Northeast corner of the United States.The complaint rates in the salt states go from less than 0.1 incident per thousand vehicles (IPTV) at 7 years in service to over 1.0 IPTV after the 12th year of service for the subject pickup trucks and utility vehicles.Most of the failures reported to ODI occurred in vehicles with more than 10 years in service.ODI?s investigation did not identify any specific defect conditions that were causing or contributing to the brake pipe failures.Nor did the analysis isolate the problem to any subject vehicle sub-populations when analyzed by vehicle type or production range.The investigation found that vehicles experiencing brake pipe corrosion failures were likely to have general patterns of excessive corrosion on the majority of the brake pipe assembly and appear to be occurring due to expected wear out for the brake pipe coating material used in the subject vehicles and the environmental conditions in severe corrosion states.A safety-related defect has not been identified at this time.Accordingly, this investigation is closed.The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist.The agency will monitor t

Component Description: ELECTRICAL SYSTEM:WIRING:FUSES AND CIRCUIT BREAKERS
Recall Campaign: 11V399
Summary Description: Siemens Circuit Breakers Failing
Summary
On November 11, 2010, Siemens Corporation (Siemens) notified the NHTSA that it had decided certain plug-in circuit breakers, manufactured between June 1, 2010, and July 31, 2010, contain a safety related defect.Siemens stated that certain circuit breakers contain a spring clip that may break or fail due to improper heat treatment during manufacturing.Should a circuit breaker spring clip break or fail, excessive temperature, arcing or thermal damage leading to a fire is possible.Should a fire occur from a circuit breaker installed into a recreational vehicle, both personal injury and property damage are possible.Siemens noted that these circuit breakers were sold under both the Siemens and Murray brand names and installed into load centers and meter combo enclosures manufactured between June 23, 2010, and August 25, 2010.This issue was assigned recall number 10E-053. Coachmen RV originally reported this issue in a Part 573 Report for their vehicles on September 15, 2010.When this EQ was opened in December 2010, only Coachmen RV, Dutchmen RV, and Keystone RV had filed subsequent Part 573 Reports for vehicles they manufactured with these circuit breakers.In response to an information request (IR) letter Siemens stated that all of their circuit breakers sold for possible use in motor vehicles were purchased by Dave Carter & Associates, a motor vehicle equipment distributor.Dave Carter & Associates' IR response noted that it sold the affected circuit breakers to Coachmen, Forest River, Keystone RV, Fleetwood RV, and Dutchmen RV.Keystone RV and Dutchmen RV had previously filed Part 573 Reports for their units, recalls 10V-606 and 10V-589, respectively.Coachmen had also filed their Part 573 Report, recall 10V-433, prior to the opening of this EQ.On July 26, 2011, RMD mailed IR letters to Forest River and Fleetwood RV.Forest River responded on August 9, 2011, that after researching the circuit breakers they purchased, their Coachmen division was the only group that used the equipment in their vehicles.Coachmen filed their Part 573 Report in September 2010, recall 10V-433.Fleetwood RV responded to their IR letter by filing a Part 573 Report on August 1, 2011, recall 11V-399, to remedy their affected motor homes.As all vehicle manufacturers using these defective circuit breakers in their vehicles have responded with appropriate measures to recall their products, this Equipment Query is closed.

Manufacturer’s Name: Mercedes-Benz USA, LLC
Component Description: EXTERIOR LIGHTING:BRAKE LIGHTS:SWITCH
Recall Campaign: 11V208
Summary Description: Brake lamp switch failure.
Summary
ODI opened the investigation based on reports that the subject vehicle brake lamp switch (switch) failure caused 1) inoperative brake lamps (stay on or fail to illuminate), and/or 2) shift interlock failure (shifter locked in park), and/or 3) the cruise control to fail to cancel with brake application.Consumers also reported the illumination of a warning lamp on the instrument panel.The switch contains three sets of electrical contacts and a (normally extended) spring loaded plunger that actuates the contacts as it moves.As installed in the vehicle, the plunger contacts the brake pedal arm and is pushed into the switch; as the driver applies the pedal the plunger extends.One set of contacts (BLS) operates the stop lamps, a second set (EWM) controls the shift interlock system, and a third set (BS) is used by an on-board diagnostic (OBD) system to monitor switch operation.The cruise control monitors the BLS signal to determine when the brake is applied, the primary way the system is disabled when set.The relative timing of contact actuation in response to plunger movement allows the OBD system to detect a switch fault.When a fault is detected a malfunction indication lamp (MIL) is illuminated (driver alert), a diagnostic trouble code (DTC) is stored (for the service technician), and cruise control operation is inhibited (as a failsafe).In its response to ODI's January 2011 information request letter, MB explained its assessment of switch failures which was based primarily on evaluation of field return failures.MB identified both 1) electrical contact and 2) mechanical switch failure mechanisms.According to MB's analysis, electrical contact failure is the predominate failure type and the failure consequence depends on which contact fails.For instance MB claims that BLS contact failures are momentary in nature and do not affect brake light operation but are nonetheless detected by the OBD system, resulting in a DTC and subsequent replacement.Electrical contact failures of the BS and EWM contacts result in a DTC also, and EWM contact failures result in the shifter being stuck in the park (which can be overridden by the consumer).Accordingly MB maintains that electrical contact failures of the switch have no safety consequence since the brake lamps remain operational and the cruise control is always disabled.MB determined that mechanical failures of the switch, which are rare in their assessment, can result from internal wear and/or increased switch operating temperatures.High temperatures occur due to overheating of the BLS contacts and can cause the internal plastic components to melt.In one scenario overheated BLS contacts may melt to the extended plunger and are damaged when the brake pedal is released resulting in the brake lights staying on.In another scenario the increased temperatures and/or internal wear can cause the plunger to stick in the fully depressed position.In this case the cruise may not cancel when the brake is applied and the driver may have to use high brake pedal forces or other means (shifting to neutral or using the cruise master switch) to disengage the cruise.Additionally the vacuum assist can be depleted if the driver pumps the brakes resulting in reduced braking effectiveness and even higher pedal forces.In its March 31, 2011 defect notification, MB stated that to remediate the potential need for excessive brake force it would conduct a safety recall (11V-208) to replace the switch with a more robustly designed component.The recall includes 136,751 model year 2000 - 2002 M-Class and model year 2000 - 2004 M-Class AMG vehicles.Owner notification letters will be mailed
